Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified make optimisation algorithms" » "modified make optimisation algorithm", "modified make optimization algorithms", "modified make estimation algorithm", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimisation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified make optimisation algorithms") OR ("modified multiobjective estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified make optimisation algorithms\") OR (\"modified multiobjective estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified make optimisation algorithms ) OR ( modified multiobjective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified make optimisation algorithms") OR ("modified multiobjective estimation algorithms"))*.
